Connecting my 2 Batteries to 1 Solar Panel

Thanks for the advice.
Now-if I connect these two batteries in oarallel- do I still need the two separate systems or I can charge them as one 8 x 2=16 AH battery ?

I thought to simply split the wires coming out of the controller to the two batteries/sockets but I came across this: http://www.morningstarcorp.com/en/su...ller.01.EN.pdf, Any suggestions? Dan G

Dan,

The circuit you presented already is a parallel circuit in regards the batteries. Looking at it, I'm assuming the diodes are there to prevent damage to the batteries & the controller if one of them is hooked up reverse. In that case, I'd use two diodes.

OOPS I neant using one controller for 2 batteries connected in parellel.

I didn't look at the circuit, but diodes are usually installed in series
between the panel and the battery to keep them from discharging through
the panel at night when it's dark and they aren't charging.

Scott,

First off, I'm a student pilot so I do not post on this forum much because I try to stay silent and learn from you all. That being said, I do have some knowledge with electronics. My initial assumption was that the diodes will act as an rectifier to prevent reverse polarity connections with the batteries. However, the solar cells could become a "load" at night and the situation you present did happen if there were not diodes there to prevent that. However, I have to believe the controller's internal circuits would prevent that from happening. So, I'll admit, my knowledge of the controller is limited. Anyone have some input on this?

Chris,
